WD SENTINEL DX4000
ADMINISTRATOR’S MANUAL
Adding Capacity by Adding a Drive
To increase capacity, simply insert an additional drive into the system. The system does not
have to be turned off or disengaged from its work to do this. The WD Sentinel server
automatically recognizes the drive, checks to see if the drive is approved for use in the
WD Sentinel server, and reconfigures the RAID to accept the new drive. At the completion of
this reconfiguration, the additional capacity is automatically available to the system. No
further operation is required.
Note: The additional drive must have a minimum available capacity of the smallest drive in
the array. For example,a3TBdrive may be added to an array made up of 2 TB
drives, but a 2 TB drive may not be added to an array composed of 3 TB drives.
Use the following steps to add a drive to your WD Sentinel server.
1. Open the door on the front of the server.
2. Unlock the handle on the empty drive bay and insert the drive into the bay, making sure
it is facing the right way and is seated properly.
3. Using some force, snap the handle shut.
4. Close the door.
